Description

  The present invention relates to an information processing apparatus and an information processing method in an apparatus for displaying video such as broadcast waves. In particular, the present invention relates to a recorded program list display device, a recorded program list display method, and a recorded program list display program that enable a user to select a program to be played back efficiently when displaying a list of recorded programs.

  With the increase in the number of digital broadcasting channels, the options for programs to be viewed by users are expanding. For example, in the case of terrestrial digital broadcasting in the Tokyo metropolitan area, over 3000 programs are broadcast in one week, and it is extremely difficult to find a program that the user wants to watch from among these programs. In such a situation, a method for finding a program that the user wants to watch includes a method using a program guide, a method using a keyword search, a method using a program recommendation function, and the like.

  The program guide displays a list of programs for each broadcasting station and time zone as represented by a latte column. When using the program guide, it is a very effective means to find a known program that the user is always watching, but to find an unknown program, it will span multiple broadcast stations, times, dates, It is a very difficult task. Keyword search is a method of displaying programs that match a keyword specified by the user. When keyword search is used, it is a very effective means to find a program when the user can accurately specify the keyword. However, if the keyword to be searched is unclear or unknown, one search result is obtained. Or a large amount of search results are output, making it difficult to find a program. As described above, the program guide and the keyword search are effective when the user's interest is clear, but are ineligible when searching for a program to be viewed in the unknown.

  On the other hand, the program recommendation function is a function that analyzes user preferences using program information of programs that the user has watched, recorded, and played back, and recommends programs that match the user preferences. When the program recommendation function is used, even if the user is a known or unknown program, it is recommended when it matches the preference, so that it is possible to prevent the program from being overlooked or to find a new program. In the program recommendation function, the user may present an unknown program. For example, the recommendation degree indicating how much the recommended program matches the user's preference and the reason why the user recommended it. By presenting to the user convenience is improved. As described above, since there are a plurality of methods for searching for a program, the user can effectively search for a program according to the situation.

  On the other hand, with the spread of digital broadcasting compatibility, recording devices equipped with a program recording function for HDD (Hard Disk Drive) have become widespread. As a method of recording a program, it is common to manually reserve recording from the program guide and record, or to directly record a program that is actually viewed, but with the increase in capacity of HDD, A variety of apparatuses are also being equipped with a function for recording programs automatically. In the function of automatically recording, there are various functions such as a function for the user to explicitly record the same program every week, a function for recording a program that hits a keyword search, and a function for recording a recommended program. For this reason, the HDD of the recording apparatus is in a situation where a large number of programs including a known program and an unknown program are easily recorded by the user, and it is difficult for the user to find a program to be reproduced from the recorded programs. It becomes. For this reason, when displaying a list of recorded programs, a display method is required to make it easier for the user to select a program that the user wants to watch from a large number of recorded programs.

  As a conventional technique related to a list display method of recorded programs, for example, in Patent Document 1, recorded programs are managed in folders classified by genre, and when there are a large number of recorded programs in a folder, EPG (Electronic A technique for generating and managing a lower folder using other attribute information (sub genre, broadcasting station, personal name, etc.) of a program that can be acquired by (Program Guide) is disclosed.

The remote control unit 210 is a device with which the user operates the automatic recording device 200, and receives operations such as menu display for recording, list display of recorded programs, channel selection, and video playback from the user.

  The recorded program management unit 211 manages recorded program information that is information of a program recorded by the automatic recording apparatus 200 and moving image data of the recorded program. The recorded program management unit 211 acquires moving image data from the stream extracted by the tuner unit 206 and stores the acquired moving image data in the HDD 203. The recorded program management unit 211 also acquires recorded program information from a program information management unit 212 described later, and stores the acquired recorded program information in the HDD 203. Each program included in the recorded program information is associated with a program included in recommendation result information (specifically described later). Furthermore, when displaying the list of recorded programs, the recorded program management unit 211 acquires the recorded program information stored at that time from the HDD 203 and outputs the acquired recorded program information to the list display processing unit 100. In addition, the recorded program management unit 211 acquires moving image data from the HDD 203 and outputs the acquired moving image data to the decoder unit 208 when the recorded program is reproduced. The configuration of the recorded program information includes various items for identifying the contents of the program as shown in FIG. 2A, for example. In the following, information on the recorded program and information on a program to be recorded (for example, a program for the next week) will be referred to as recorded program information and future program information, respectively. Similar to the recorded program information, the future program information also has the configuration shown in FIG. 2A. As shown in FIG. 2B, these pieces of information are recorded in the record R301 according to the number of programs, for example. Are stored in the HDD 203 in the format of ~ R305.

  As shown in FIG. 2A, the recorded program information and future program information include the type of broadcast wave and its channel, the genre of the program, the date and time (broadcast date and broadcast time) when the program is broadcast, and the title of the program. And the subtitle, the performer of the program, and information indicating the presence or absence of parental lock. In the example shown in FIG. 2A, the first episode of the Hitachi drama was broadcast (or broadcast) on channel 1 of digital terrestrial broadcasting from 21:00 to 22:00 on January 1, 2012. It is shown that. In addition, performers 1 to 4 appear in this program, and viewing restrictions are not imposed by parental lock. Note that the recorded program information and future program information are output by the number of programs. In the present embodiment, the future program information and the recorded program information are described as having the same configuration in consideration of the ease of history management. However, if this information is included, In particular, they may not have the same configuration.

  Specifically, as will be described later, the program information management unit 212 extracts a future information program from the stream at a predetermined timing, and the recorded program management unit 211 views a program included in the future information program according to an instruction from the user. When recording or recording, the history management unit 213 acquires history information (described later) of the program. Further, the program recommendation calculation unit 214 compares the history information with the future program information to be extracted thereafter, and outputs recommendation result information (described later) indicating a program to be recommended to the user. The recorded program list processing unit 100 However, since the program matching the recommendation result information is displayed on the display unit 209 from the program information in the future, the user can efficiently record the program by displaying the program to be recommended to the user on the display unit 209. You can find the program you want to watch from the program.

  The program information management unit 212 manages all programs of receivable broadcast waves and channels and future program information of the programs. The program information management unit 212 extracts future program information from the stream received by the tuner unit 206 and stores the extracted future program information in the HDD 203. In addition, the program information management unit 212 displays a program table for displaying a list of programs for each broadcasting station and time zone as represented by a latte column in the automatic recording apparatus 200, and programs to be automatically recorded by keywords. 2, the program for recommending a program that matches the user's preference from the program table (hereinafter referred to as recommended program calculation) is acquired from the HDD 203 as shown in FIG. Output to the history management unit 213. Note that the future program information does not need to have the configuration shown in FIG. 2A as described above, and the above-described program table display, recorded program list display, search for programs to be automatically recorded by keywords, and It only needs to include information necessary for program recommendation calculation. In addition, the program information management unit 212 acquires recommendation result information that is a result of the recommended program calculation of the program performed by the program recommendation processing unit 214 from the program recommendation processing unit 214, and obtains the acquired recommendation result information and future program information. The data is stored in the HDD 203 in association with each other and output to the list display processing unit 100.

  The history management unit 213 manages history information including video viewing, recording, and playback history. The history management unit 213 records history information when the remote controller 210 accepts a video viewing / recording / playback operation from a user. The history management unit 213 acquires future program information managed by the program information management unit 212 during viewing and recording, and stores the history together with the acquired future program information in the HDD 203. Further, at the time of reproduction, the history management unit 213 acquires the recorded program information managed by the program information management unit 212 and associates the history with the acquired recorded program information and stores it in the HDD 203. In this way, the history management unit 213 centrally manages the history (program viewing history, recording history, reproduction history) together with the recorded program information and future program information.

  Further, the history management unit 213 outputs the viewing history, recording history, and playback history stored in the HDD 203 to the program recommendation processing unit 214. Each of the history information stores an operation history such as viewed, recorded, and played back. For example, when the time of 50% or more of the entire program has elapsed, the history management unit 213 Stores the program as viewed, recorded, or played. About how much time has passed, it can be set in various patterns such as the genre and time zone of the program, whether it is a series, etc.

  FIG. 3 is an example of history information managed by the history management unit 213. The items C101 to C109 held as history information are the same as the items included in the recorded program information and future program information shown in FIG. The history management unit 213 stores these items in the HDD 203 like records R101 to R108 in a history format for each program. Although not particularly shown in FIG. 3, actually, the history information further stores moving image data, viewing / recording of the moving image, start time and end time of the reproduction history, and the like.

  The program recommendation processing unit 214 recommends a program that matches the user's preference among future programs to be broadcast in the future. The program recommendation processing unit 214 performs recommended program calculation using a predetermined calculation method, and outputs recommendation result information. The program recommendation processing unit 214 performs recommended program calculation at an instruction from the user or at a timing preset by the automatic recording apparatus 200 (for example, once a day, once a week, etc.).

  When calculating a recommended program, the program recommendation processing unit 214 acquires history information from the history management unit 213, acquires future program information from the program information management unit 212, calculates a distance between the history information and future program information, Recommend a program that matches the user's preferences. For example, the program recommendation processing unit 214 determines a recommended program by determining how much each item included in the recorded program information and the future program information matches (the size of the item). By comparing the degree of coincidence of the contents for each item of the program information, it is possible to determine whether or not the history information and the future program information are more similar, and to select a program to be recommended .

  For example, the program recommendation processing unit 214 performs “broadcast wave”, “channel”, “genre”, “broadcast date”, “broadcast time”, “title”, “subtitle” included in the future program information shown in FIG. 2A. , “Performer”, “Parental Lock”, etc., and the items included in the history information shown in FIG. 3 are compared with the same items, and one item more than a certain number is compared. The number of matching items is determined so that the user has a higher preference for viewing the program, and it is determined that the program should be strongly and strongly recommended. To do.

  In addition, the program recommendation processing unit 214 determines the priority order of items that the user attaches importance to or changes the order of items that match between the future program information and the history information. The recommended program is calculated using weighting information indicating the importance of each item. FIG. 4 is a diagram illustrating an example of weighting information. As shown in FIG. 4, the weighting information includes a channel, a genre, a broadcast time, a title, and a performer. These items C201 to C205 are the same as the items shown in FIGS. 2A and 3. In the present embodiment, these five items are defined as weighting information, but other items such as a broadcast date may be set.

  In FIG. 4, among the values (evaluation values) of items included in the weighting information, the evaluation value of “title” is set to “20”, which is the largest value, and is set as an item representing the highest user preference. And the evaluation value of the broadcast time is “1”, which is set low as an item representing the user's preference. In the present embodiment, the evaluation value of the title is set as an item that expresses the highest user preference, but it can be changed as appropriate by the user.

  When each item is matched between the future program information and the history information, the program recommendation processing unit 214 sequentially adds the evaluation value indicated by the item of the weighting information corresponding to the item for each item. For example, the program recommendation processing unit 214 compares certain future program information with certain history information, and if “genre” and “performer” match, “genre” among the items of the weighting information shown in FIG. "Evaluation value" 2 "and evaluation value" 5 "of" performer "are obtained, and the evaluation value of the entire program is calculated as" 7 ". Using such a method, the program recommendation processing unit 214 calculates evaluation values for all history information and future program information, and calculates the evaluation values of the programs in all future program information by adding them. To do. And the program recommendation process part 214 can recommend the program which matched a user preference by arranging in order with the calculated evaluation value high.

  Further, when there are repeated items that match the future program information and the history information, the program recommendation processing unit 214 determines that the user is frequently watching or recording the program, and multiplies the evaluation value by that number. To do. Then, when the evaluation value is calculated for each program, the program recommendation processing unit 214 outputs an evaluation value calculation table in which the evaluation value is calculated for each program.

  FIG. 5 is a diagram illustrating an example of the evaluation value calculation table. As shown in FIG. 5, the evaluation value calculation table includes a program title, a subtitle, a recommendation level, a recommendation reason, an evaluation value of the program, and an evaluation of each item to be calculated included in the weighting information. A total of values is stored in association with each other. The recommendation level is information indicating the strength and size of recommending the program, and the reason for recommendation is information indicating the reason for recommending the program with the strength and size indicated by the recommendation level.

  In the example illustrated in FIG. 5, when the program recommendation processing unit 214 refers to the future program information illustrated in FIG. 2B and selects a program (record R301) whose genre is “drama”, the genre “drama” is used as a key. With reference to the history information shown in FIG. 3, it is determined that there are two programs (records R101 and R106) whose genre is “drama”. Further, the program recommendation processing unit 214 refers to the weighting information shown in FIG. 4 using the genre “drama” as a key, acquires the evaluation value “2” corresponding to the genre, and obtains the program of the title “drama A”. The evaluation value of the “genre” item is set as 2 cases × 2 = 4. The program recommendation processing unit 214 calculates the other items in the same way, and calculates the evaluation value of the entire program by adding the calculated evaluation values of the items. For example, the evaluation value calculation table for the second episode of the title “Drama A” is set as items C405 to C410 of the record R401 shown in FIG. 5, and the evaluation value for each program is calculated. In the example shown in FIG. 5, the program recommendation processing unit 214 has a program evaluation value “26” for the title “Drama A”, and is a program that most closely matches the user's preference as compared to other title programs. Judge that there is.

  Further, the program recommendation processing unit 214 identifies the item showing the highest value among the evaluation values of each item, and sets the recommendation level of the program according to the height of the evaluation value. For example, the maximum evaluation value of a program is 30, a program with an evaluation value of 15 to 30 (about half of the whole) is a three-star program, and an evaluation value is about 1/4 to half of the whole of 8 to 15) When a program is classified as a two-star program and a program with an evaluation value of 0 to 7 (up to about ¼ of the entire program) is classified as a one-star program, the recommendation degree of “Drama A” is set to three stars. In the same manner, the recommendation degree of the program is set higher as the evaluation value of the program is larger.

  And the program recommendation process part 214 will set the reason (recommendation reason) which set the recommendation degree of the program, if the recommendation degree of a program is set. The program recommendation processing unit 214 identifies, for each program output to the evaluation value calculation table, an item having the highest evaluation value among the evaluation values of the program (that is, an item that reflects the user's preference most). The name of the item is set as the reason for recommendation. For example, for the program with the title “Drama A”, the program recommendation processing unit 214 sets the word “Frequently viewed title” as the reason for recommendation because the evaluation value of “Title” is the highest. Similarly, the name of the item having the highest evaluation value is set as the recommendation reason for each program. In this way, by setting the name of the item having the highest evaluation value of a certain program as the recommendation reason, when the program recommendation processing unit 214 recommends a program that the user is not interested in, the recommendation reason is effectively determined by the user. The user can be convinced by seeing the reason for the recommendation.

  Then, the program recommendation processing unit 214 outputs recommendation result information indicating the recommendation result of the program from the evaluation value calculation table. FIG. 6 is a diagram illustrating an example of recommendation result information. As shown in FIG. 6, “Title”, “Subtitle”, “Recommendation Level”, and “Reason for Recommendation” included in the evaluation value calculation table are extracted from the recommendation result information. Since these items are the same as the items in the evaluation value calculation table, the description thereof is omitted here. The program recommendation processing unit 214 stores recommendation result information in the HDD 203 in association with a program included in the future program information. As will be described later, the recommendation result information is read by the list display processing unit 100 when a program is recorded or viewed and displayed on the display unit 209. Note that the program recommendation processing unit 214, for example, when the recommendation result information includes a program having a recommendation degree of no star to three stars, for example, automatically records only a program of two stars or more, and the number of stars. It is also possible to determine whether or not to automatically record according to (that is, classified into the recommendation level). As for the reason for recommendation, for example, it is also possible to automatically record only programs of genres that are often viewed.

  As described above, each unit described above realizes a function for the automatic recording apparatus 200 to operate as a DTV, an HDD recorder, and a PC. However, viewing, recording and playback of a broadcast stream, and content information of a broadcast and a recorded program However, the present invention is not limited to this configuration as long as it can be managed and operated from the outside. Next, returning to FIG. 1, the list display unit 100 will be described.

  The list display processing unit 100 displays the recorded program information on the display unit 209 in a list format. Also, the list display processing unit 100 displays the recorded program information displayed in the list format on the display unit 209 after filtering and sorting with a predetermined key. As keys used for filtering and sorting of recorded programs, when using each item included in the recorded program information as shown in FIG. 2, the recommendation result information including the recommendation degree derived by the program recommendation calculation and the recommendation reason And so on.

  When the program information processing unit 151 receives an instruction to display each item of the recorded program information on the display unit 209 in a list format using the remote controller 210 as a key and an instruction to filter or sort each item, FIG. A list of programs is displayed using each item included in the recorded program information shown in FIG.

  When the recommendation level processing unit 152 receives an instruction to display on the display unit 209 in a list format using the recommendation level included in the recommendation result information as a key via the remote controller 210, the recommendation level processing unit 152 is included in the recommendation result information illustrated in FIG. A list of programs is displayed using the recommendation level as a key.

  When the recommendation reason processing unit 153 receives an instruction to display the list on the display unit 209 using the recommendation reason included in the recommendation result information as a key from the user via the remote controller 210, the recommendation reason processing unit 153 is included in the recommendation result information illustrated in FIG. A list of programs is displayed using the reason for recommendation as a key.

  Even when the recorded program information is displayed under any one of the conditions of each of these processing units, further filtering and sorting can be performed by other processing units. For example, even if the recommendation level processing unit 152 filters the recorded program information by the recommendation level, the recommendation reason processing unit 153 can further filter the recorded program information by the recommendation reason.

  FIG. 7 is a diagram illustrating a state in which the list display processing unit 100 displays recorded program information on the display unit 209 in a list format. In the example illustrated in FIG. 7, the list display processing unit 100 includes a group (second display) for displaying a group indicating a display method of recorded program information and each item of the recorded program information classified by the group by folders. The recorded program information is displayed in a list format in accordance with a first hierarchy to a third hierarchy and a list display hierarchy. For example, when displaying recorded program information on the display unit 209 without virtually categorizing the recorded program information (group 1), the list display processing unit 100 selects a certain item (“genre” in the example shown in FIG. 7) of the recorded program information. When the recorded program information is displayed on the display unit 209 by classifying it into the set values (group 2), the recorded program information when the automatic recording apparatus 200 automatically records the program with reference to the recommendation result information is displayed. When displaying on the display unit 209 (group 3), it is displayed separately. The recorded program information displayed as group 2 is not limited to “genre”, but also “broadcast wave”, “channel”, “broadcast date”, “broadcast time”, “title”, “performer”, “ It is also possible to classify by the presence or absence of “parental lock”.

  The list display processing unit 100 classifies and displays “all”, “genre”, and “automatic recording” as groups 1 to 3 in the first hierarchy, and displays folders from the user via the remote controller 210. When is selected, the recorded program list is filtered according to the filter condition of the folder. For example, when “genre” is selected in the first hierarchy, the list display processing unit 100 selects from “drama”, “music”, “variety”, “soccer”, and “baseball” in the second hierarchy. Further, the filtering is performed so that the selected folder (and the folders below it) are displayed. Similarly, when a folder is further selected in the second hierarchy, the list display processing unit 100 performs filtering so that the folder and the program list in the lower hierarchy are displayed. The “all” folder is a folder for displaying recorded programs other than automatically recorded programs without filtering the recorded program list. The “genre” folder is a folder for filtering each genre with respect to a recorded program list excluding automatically recorded programs.

  Further, the “automatic recording” folder is a folder for filtering the recorded program list only for the recorded program automatically recorded with respect to the recorded program list, and the contents of the recommendation result information shown in FIG. 6 are displayed. Is done.

  Specifically, the list display processing unit 100 acquires the recommendation result information shown in FIG. 6, and when the “automatic recording” folder is selected from the user via the remote controller 210, the list display processing unit 100 recommends it as a second-level folder. “Recommendation level” (C503) and “Reason for recommendation” (C504) of the result information are displayed in a folder format. Furthermore, when the “recommendation level” folder in the second hierarchy is selected, the list display processing unit 100 displays evaluation folders indicating specific evaluation levels (no stars to three stars). If the evaluation folder is selected, the title (C501) of the evaluated program is displayed. On the other hand, when the “automatic recording” folder is selected by the user via the remote control 210 and the “recommendation reason” folder in the second layer is selected, the list display processing unit 100 recommends a specific recommendation reason. The reason folder is displayed, and when these recommendation reason folders are selected, the title (C501) of the program recommended for the reason is displayed.

  The parental lock is for setting whether or not to display the program when the list display processing unit 100 displays the recorded program information on the display unit 209 in a list format. When the parental lock value of the program is set to “necessary” (not displayed on the display unit 209) in advance, the list display processing unit 100 filters the program when displaying the recorded program information in a list format. Then, the display unit 209 is controlled not to display. Next, a process (list display process) when the recorded program information is displayed in a list format in the automatic recording apparatus 200 will be described.

  FIG. 8 is a flowchart showing the processing procedure of the list display processing. Hereinafter, a case where a list of recorded program information as shown in FIG. 7 is displayed on the display unit 209 will be described.

  As shown in FIG. 8, in the list display process, first, when the standard input / output unit 207 receives an instruction for displaying a list of recorded program information from the user via the remote controller 210 (step S801), the list display is performed. The processing unit 100 acquires recorded program information from the recorded program management unit 211, and displays a list of recorded program information on the display unit 209 (step S802).

  For example, the list display processing unit 100 displays a list of recorded program information as shown in FIG. In the list of recorded program information, when the recorded program is virtually hierarchized by folders, the user operates the remote controller 210 to select a displayed folder, and the standard input / output unit 207 receives the instruction, the display processing is performed. The program information processing unit 151 of the unit 100 displays the result of filtering the list of recorded program information. In the example shown in FIG. 7, the folder structure from the first layer to the third layer is used, and the layer that displays the list of recorded programs that is the filtered result is the lowest list display layer, but the folder layer is necessary. Any number of layers is acceptable.

  Then, when the automatic recording folder is selected from the folders displayed by the user via the remote controller 210 and the standard input / output unit 207 receives the instruction, the list display processing unit 100 receives the instruction from the recorded program management unit 211. The recommendation result information at the time is acquired, and the acquired recommendation result information is displayed on the display unit 209 as shown in FIG. 7 (step S803). For example, the list display processing unit 100 acquires the recommendation degree C503 and the recommendation reason C504 of the recommendation result information shown in FIG. 6, and displays them on the second and third layers of the recorded program information list shown in FIG. To do.

  Thereafter, either the “recommendation level” or the “reason for recommendation” of the second layer is selected from the displayed recommendation result information via the remote controller 210, and the specific recommendation level value of the third layer is further selected. Alternatively, when a specific recommendation reason is selected, the recommendation level processing unit 152 or the recommendation reason processing unit 153 performs filtering using the selected value of the third layer or the recommendation reason as a key, for example, the number of stars Sorting is performed by a method such as descending order or alphabetical order (step S804), and a list display layer that is a lower hierarchy is displayed (step S805).

  For example, when “recommendation level” is selected in the second level, the recommendation level processing unit 152 displays a specific value (no star to three stars) of the recommendation level in the third level, and further displays the recommendation level. When a specific value is selected, the recorded program corresponding to the selected recommendation level is filtered and displayed on the fourth layer. Further, for example, when “recommendation reason” is selected in the second layer, the recommendation reason processing unit 153 displays specific values (reviewed channels, frequently viewed channels, etc.) of recommendation reasons in the third layer, Further, when a specific value for the recommendation reason is selected, the title of the recorded program corresponding to the selected recommendation reason is filtered and displayed on the fourth layer. When the process of step S805 ends, the list display process shown in FIG. 8 ends.

  As described above, since the automatic recording apparatus 200 performs the list display process shown in FIG. 8, the user can efficiently find a program to be viewed from the recorded program from time to time. Specifically, the user can efficiently select a recorded program to be played back in accordance with the recommendation degree of program recommendation and the reason for recommendation. For example, when the recommendation level is expressed by the number of stars (“☆☆☆”, “☆☆”, “☆”) in descending order, when the list display processing unit 10 displays the recorded program list, the user uses the remote control 210 to display the list of recorded programs. When a three-star recommendation level (“☆☆☆”) is selected, only the programs in the folder are displayed on the display unit 209, so that only programs that match the user's preference can be displayed. Only programs that the user is interested in can be displayed quickly.

  FIG. 9 is an image diagram showing a concept until the automatic recording apparatus 200 performs a list display process and displays a list of recorded program information on the display unit 209. As shown in FIG. 9, first, when the automatic recording apparatus 200 receives future program information, the automatic recording apparatus 200 extracts a program to be recorded as recorded program information by a recording operation via the remote controller 210 from the user, and uses the actual data. While storing in association with certain moving image data, the history information of the program that has been viewed or recorded is stored.

  Then, the automatic recording apparatus 200 executes the above-described program recommendation calculation using the stored history information, future program information, and weighting information, and outputs an evaluation value calculation table and recommendation result information. Further, when receiving the future program information at the next timing, the automatic recording apparatus 200 associates the future program information with the recommendation result information, displays the above-mentioned recorded program list on the display unit 209, and is selected therein. A program is extracted as recorded program information, and stored in association with recommendation result information and moving image data as actual data. On the other hand, the automatically recorded image value 200 stores history information of a program that has been viewed or recorded. By periodically performing such a series of flow procedures, it becomes possible to quickly display only programs that better match the user's preference.

  In the first embodiment, the list display processing unit 100 of the automatic recording device 200 generates each folder of the recommendation level and the reason for recommendation for the automatically recorded program (group 3), and performs the filtering / sorting process. It was. However, depending on the user, there may be cases where it is desired to generate and display each folder of the recommendation level and the reason for recommendation for programs other than the automatically recorded program. Therefore, in the present embodiment, a case will be described in which each folder of recommendation level and recommendation reason is generated and filtering / sorting processing is performed for all programs including automatically recorded programs.

  In this embodiment, the program recommendation processing unit 214 targets all programs stored as the history information shown in FIG. 3, future program information shown in FIG. 2B, history information, and the information shown in FIG. 4. Using the weighting information, the program recommendation calculation is executed as in the first embodiment. In the case of the first embodiment, when there is a program of the same genre between the future program information and the history information, the evaluation value is multiplied and set. However, in the second embodiment, the programs included in all the history information are recorded programs. Therefore, the program recommendation processing unit 214 calculates the evaluation value for each program using the evaluation value as it is, and outputs the recommendation result information.

  FIG. 10 is a diagram illustrating an example of recommendation result information in the second embodiment. As shown in FIG. 10, in the recommendation result information in the second embodiment, the recommendation level and the reason for recommendation are set for all programs (R601 to R608) included in the history information. When the recommendation result information is output and then the standard input / output unit 207 receives an instruction to display a list of recorded program information from the user via the remote controller 210, the list display processing unit 100 displays the recorded program management unit. Recorded program information is acquired from 211, and recommendation result information output by the program recommendation processing unit 214 is acquired, and a list of recorded program information is displayed on the display unit 209.

  FIG. 11 is a diagram illustrating how the list display processing unit 100 displays recorded program information on the display unit 209 in a list format in the second embodiment. As shown in FIG. 11, in Example 2, the list display processing unit 100 displays a list of recorded programs for all programs included in the history information. At this time, for example, the list display processing unit 100 acquires “recommendation level” and “reason for recommendation” from the recommendation result information on the first level and displays them on the display unit 209, and further displays the specific recommendation level on the second level. Displays a simple value (no stars to three stars). When a specific value of the recommendation level is selected, the recommendation level processing unit 152 filters the recorded programs corresponding to the selected recommendation level and displays them on the fourth layer. In addition, for example, when “recommendation reason” is selected in the first layer, the list display processing unit 100 displays a specific value of the recommendation reason (a channel often viewed, a channel often viewed, etc.) in the second layer. Then, when a specific value of the recommendation reason is selected, the recommendation reason processing unit 153 filters the title of the recorded program corresponding to the selected recommendation reason and displays it on the fourth layer. In this embodiment, since all programs included in the history information are targeted, subtitles are displayed in addition to titles.

  As described above, the list display processing unit 100 displays a list of recorded programs by the recommendation display, the folder display by the recommendation reason, and the filtering process for all the programs stored in the history information regardless of whether or not the automatic recording is performed. Can be displayed. As for the filtering and sorting methods, it is possible to perform filtering or sorting by various items as in the case of the first embodiment.

  In the first embodiment and the second embodiment, the list display processing unit 100 displays, filters, and sorts a recorded program list by using a hierarchical folder display. There is also a need to select a program you want to watch more directly than to display. Therefore, in this embodiment, by displaying (collectively displaying) the program name for each “genre” included in the future program information or history information, and “recommendation degree” and “reason for recommendation” included in the recommendation result information, A case where a program is selected more directly will be described.

  FIG. 12 is a diagram illustrating how the list display processing unit 100 displays recorded program information on the display unit 209 in a list format in the third embodiment. As shown in FIG. 12, when displaying recorded program information, the list display processing unit 100 extracts “genre”, “title”, and “subtitle” items included in future program information or history information, and recommends results. The “recommendation degree” and “recommendation reason” included in the information are extracted, and “title” and “subtitle” are displayed as the program name for each of these “genre”, “recommendation degree”, and “reason for recommendation”. In this case, the recommendation level processing unit 152 sorts by the number of stars of the recommendation level, and the recommendation reason processing unit 153 sorts by the specific content of the recommendation reason. For example, when the user selects the recommendation level column via the remote controller 210, the recommendation level processing unit 152 of the list display processing unit 100 sorts the items in descending order of the number of stars. When the user selects a recommendation reason column via the remote controller 210, the recommendation reason processing unit 153 of the list display processing unit 100 sorts in alphabetical order.

  In this embodiment, the case where the “recommendation degree” and the “reason for recommendation” are sorted in this order has been described. However, it is of course possible to sort each of these items one by one or by changing the order. In this case, it is possible to accurately respond to diversifying user needs.

  In the present embodiment, the sort display is performed when the recorded programs are collectively displayed. However, the “automatic recording” folder and the “genre” folder as shown in the first and second embodiments are provided, and the list display processing unit 100 It is also possible to filter the recorded program list according to the folder selected by the user, and display the programs at a time after performing the filter processing.

  In the third embodiment, the list display processing unit 100 displays a program name for each “genre” included in future program information or history information, and “recommendation degree” and “reason for recommendation” included in recommendation result information (collective display). However, some users may want to specify filtering conditions in a more understandable manner. Therefore, in this embodiment, a recommendation degree filter item for filtering according to the recommendation degree is provided at a position different from the recorded program list, and the filtering condition is specified in a form that is more easily understood by the user, so that it can be more visually recognized. A case where the recorded program list is filtered for easy understanding will be described.

  FIG. 13 is a diagram illustrating how the list display processing unit 100 displays recorded program information on the display unit 209 in a list format in the fourth embodiment. As shown in FIG. 13, when displaying recorded program information, the list display processing unit 100 extracts “genre”, “title”, and “subtitle” items included in future program information or history information, and recommends results. The “recommendation degree” and “recommendation reason” included in the information are extracted, and “title” and “subtitle” are displayed as the program name for each of these “genre”, “recommendation degree”, and “reason for recommendation”. In this case, the list display processing unit 100 displays “recommendation degree” at a position different from the other items on the screen. When the number of recommendation stars displayed at the other position is selected, the recommendation level processing unit 152 filters and displays only the programs with the number of stars. FIG. 13 shows a case where only two-star and three-star programs are displayed.

  In the present embodiment, the case where the program to be displayed is filtered by the “recommendation degree” has been described, but it is of course possible to filter by the “reason for recommendation” or by combining these items. In this case, as in the case of the third embodiment, it is possible to accurately meet the needs of diversifying users.

  In the present embodiment, the sort display is performed when the recorded programs are collectively displayed. However, as in the case of the third embodiment, the “automatic recording” folder and the “genre” folder as shown in the first and second embodiments are used. The list display processing unit 100 can filter the recorded program list according to the folder selected by the user, and can display the programs at a time after performing the filtering process.

  In the first to fourth embodiments, when recording a broadcast program, the case where a program to be recorded is filtered or sorted to display a list of recorded programs has been described. There is no particular limitation as long as the reason for recommendation can be set. For example, in the case of content such as a net video, Internet website, Internet shopping, software application, etc. that can be viewed with a browser or the like instead of a broadcasted program, the user's usage history is the same as the history information shown in FIG. And use history, recommended using the same information as the future program information as shown in FIG. 2B, video program information, site information, shopping information, application information, and weighting information shown in FIG. As long as the recommendation result information including the degree and the reason for recommendation can be output, the present invention can be applied in the same manner as the automatic recording apparatus shown in the first to fourth embodiments.

  Further, in the first to fourth embodiments, when the list display processing unit 100 displays a list of recorded programs, the list is displayed on the display unit 209 of the automatic recording apparatus 200. For example, the connection is made via a network. It is also possible to display information similar to the information displayed in the first to fourth embodiments on a display device such as a display different from the automatic recording device 200 that has been provided. Similarly, when performing filtering and sorting by recommendation level and recommendation reason, filtering and sorting are performed by a device other than the automatic recording device 200, and the result is displayed on the automatic recording device 200 or connected via a network. Further, it may be displayed on a display device different from the automatic recording device 200. In this case, the automatic recording apparatus 200 requests filtering and sorting conditions from the apparatus that performs filtering and sorting, and acquires and displays the result.
